A provisional survey of the interaction between net photosynthetic rate, respiratory rate, and thallus water content in some New Zealand cryptogams

open access: yes, 1980
The effect of water content on photosynthetic and respiratory rates in eight lichen species and one bryophyte species were studied using an injection infrared gas analyser technique. All species snowed a strong relationship between net assimilation rate (

The Age and Origin of Block Deposits in the Victorian Alps, Australia

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in

Characterization and Expression Analysis of the Sterol C-5 Desaturase Gene PcERG3 in the Mycobiont of the Lichen Peltigera canina Under Abiotic Stresses

open access: yesMicrobiology Research
Lichens, symbiotic organisms with a high tolerance to harsh environments, possess a greater diversity of sterols than other organisms. Sterols are involved in maintaining membrane integrity, hormone biosynthesis, and signal transduction.

Conservation status of species used in the UK herbal medicine industry

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Given the ongoing biodiversity crisis, sustainable use and management of medicinal plants is critical. We assessed the conservation status, threats and conservation actions of 298 species sold by UK suppliers to medical herbalists. We found that most species used are unevaluated, representing a gap in conservation knowledge, and of those with ...

Looking backward to move forward: Enhancing metadata in scientific collections through interdisciplinary collaboration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Early modern herbaria house important and useful data on historic environments. However, their contents are often inhospitable to scientific use. Despite this challenge, once their contents have been deciphered, such specimens present novel research opportunities.
